Shifter illumination on 92 140 300SE not working. Was able to open shifter area by removing ash try and wood trim with no problem. Noticed that there were two wires with what look like spade connectors on the ends--obviously not plugged into what they're supposed to be plugged into. These were a brown wire which I assume is the ground wire and a gray wire with blue stripe. Can not figure out where these are supposed to plug into. Can someone help me here ?
